3548	test_filesystem_with_cli_in_subprocess mutates os.environ a bunch	exarkun		"It's not clear what effect these mutations may have on the test process itself but they clearly can have an effect on child processes.

There are two places this happens:

{{{
env = kwargs.get(""env"", os.environ)
# Python warnings from the child process don't matter.
env[""PYTHONWARNINGS""] = ""ignore""
}}}

and

{{{
env = os.environ
env['http_proxy'] = env['HTTP_PROXY'] = ""http://127.0.0.0:12345""  # invalid address
}}}
